Yes, that is true. But the amount of spam coming through spammers that
are harvesting keyservers is much less compared to posting in newsgroups.

Yes, it is possible, but that breaks any encryption front end (like
enigmail) which automatically searches the right key by searching for
the email address in the key description. At least (with enigmail) nasty
work is necessary to manually search the right key for the recipient
when the mail adresses on the key doesn't match the real recipient
address. Encryption with some other front end may not work at all.

Yes, it matters. You won't be able to phone to somebody if he hasn't got
a phone. (Roughly) the same is true for encrypted email.
